WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 787,818, dated .AprillS, 1905.

Application filed June 15, 1904. Serial No. 212,598. I

To r177 1071/0721 it lll/fl/ l/ cone/a772,:

Be it known that I, \VILLIAM J. BAKER, residing at Newport, in the county of Campbell and State of Kentucky, have invented certain new and useful Improvements in \Vindow- Screens, of which the following is a specification.

This invention relates to improvements in metallic-frame screens; and it comprehemls a novel and simple means for securing the screen-wire to the frame in such a manner that in case of wear or in case of the screen becoming broken the said screen-wire can be readily removed and replaced by a new screenwire.

My invention also seeks to provide an improved construction of frame whereby the wire can be firmly held in such a manner that water cannot enter the inside of the metal rim or frame, the correlation of the screen and the clamping portions of the frame being such as to deflect water that may trickle down the screen to the outside of the frame.

In its more complete make-up my invention includes a special construction of metalframe and particularly seeks to provide animprovement on the windowscreen disclosed by my Patent No. 678,216, patented July 9, 1901.

\Yith other objects in view, which will be hereinafter fully apparent, my invention consists in certain novel construction, arrangement, and combination of parts, all of which will be first described in detail, and then specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure l is a face view of a window-screen with my improvement applied. Fig 2 is a perspective of the screen detached from the window-casing. Fig. 3 is a cross-section on the line 3 3 of Fig. 2. Fig. l is a similar view, the parts of the frame being separated. Fig. 5 is a detail perspective view showing the construction of frame disclosed in Figs. 1 to l, inclusive. Fig. 6 is a view of a slightlymodilied form of my invention. Fig. '7 is a similar view, the parts of the frame being separated. Figs. 8 and 9 are views showing the manner of assembling parts of the frame shown in Figs. 3 and 6, respectively.

edge, as at 3, and then bent upwardly, as at 3, after which the upper edge of the member 3 terminates in the bent-over portion 3, hook-shaped in cross-section for a purpose presently to appear. The piece 3 also includes a flat .bottom 3" and an outer side por-' tion 3, extending parallel with the inner side portion of the member 3, which portion 3 is also provided with an inwardly-projecting bead 3, disposed opposite to the bead 3. The portion 3 has its upper edge terminating in an inwardly-extending member 3, concaved in cross-section, which cooperates with a convex imvardlyextending member 3" of the second piece 3", which piece 3" is bent inwardly near its upper edge, as at 3", and upwardly to form an interlockingedge 3", which interlocks with the hook edge 3 of the piece 3, as clearly shown in the drawings. The screen-wire S is held between the pieces 3 and the hook edge 3" and the edge 3" to secure the said screen-wire to the frame.

To raise and lower the screen with respect to the wimlowcasing, I may provide the ordinary handles, as shown in Figs. 1 and 2.

The rod 4 is interposed in the frame between the bcads 3 3" and the bottom 3".

By making the parts 3" 3' curved in crosssection the parts may be assembled, as shown in .Fig. 8, by simply inserting the edge 3 in the hook edge 2 and springing the member 3' into place on the member 3", when the members will be securely interlocked to prevent them from becomingseparated by accidentor otherwise.

In Figs. (5 and 7 l have shown a slightlymodil'icd form of my invention, in which the interlocking members 3" 3' are disposed at the bottom of the screen-section, and in this case the portion 3 is disposed with the member 5" extending to the bottom of the screen, and in the form shown in Fig. (5 the bead 3" is formed in the member 3. The manner of assembling the parts of the frame shown in Figs. 6 and 7 will be readily understood by reference to Fig. 9.

In its practical construction my improved window-screen includes the usual rod or stiffener-frame 4, before referred to, upon which the metallic wire-cloth-clamping members are held In my form of screen the metal clamping members constituting the sides, top, and bottom may be braced or connected at the meeting ends or corners by angled corner-pieces 2 of any approved construction, as the said corner-fasteners form per 86 no part of my invention. In its more essential feature it relates to the peculiar construction of the wirecloth-holding metal portions, as shown.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that by constructing the screen with a metal frame consisting of interlocking parts, as shown, the screen can be readily removed or replaced into the frame after thesame has been set up by simply unlocking or removing the part 5 from the part 3. Again, it will be seen that one of the most essential advantages of my invention over what has heretofore been done in the art is that a very simple and inexpensive means is provided for fit:

ting the cloth to the frame and for speedily removing the worn-out screen-cloth when it is desired to rewire the frame. By reason of the clamping ends 8 being arranged so that the extreme edge of the hook end 3 projects downwardly the said edge 3 Will serve as a watershed to cause the water to run toward the outside of the screen rather than toward the inside of the screen and also serve to prevent the Water getting into the inside of the hollow frame member.

While I prefer to use the ordinary form of stiffener-rod, yet I desire it understood that it is not absolutely necessary that the said rod be used. It may be omitted entirely or used only for the top and bottom sections with angled corner-pieces sufiicient to add rigidity to the corners of the frame. The sliding edges of the sides of the screen may be made to run in grooves in the window or on other suitable guide members, the bearing-springs 13 being provided to hold the screen-frame in position on the window-casing.

From the foregoing, taken in connection with the accompanying drawings, itis thought that the advantages, complete construction, and operation of my invention will be readily understood by those skilled in the art to which I claim, and desireto secure by Letters Patent, is

1. In a metallic window-frame, a springmetal frame-section, having a flat base and parallel sides, the upper end of one of said sides being bent inwardly and terminating in a hook-shaped edge, the upper end of the other side being bent inwardly at an angle thereto,

.a locking member comprising a sheet-metal strip having a straight edge for entering the hook-shaped edge of the frame-section, and having its other edge bent inwardly to 006perate with the inwardly-bent edge of the second side portion of the frame-section all being arranged substantially as shown whereby to bring the body of the screen in a plane outside of the frame to prevent the water trickling down into the frame-section as set forth.

2. A screen comprising a metallic frame composed of side, top and bottom sections 3, and a screen-wire S, each of said sections 3 comprising a pair of sheet-metal strips 3 3 the strip 3 being provided with a bent-over edge, hook-shaped in cross-section, the strip 3 having its upper edgeinterlocked with said bent-over hook-shaped edge and having its lower portion provided with an inwardly-projecting member 3' curved in cross-section, said strip 3 having a correspondingly-formed inwardly-projecting portion 3 to interlock with the member 3", the screen-wire being disposed between the pair of metal strips sub= stantially as shown and described.

3. A screen-wire-clamping member, comprising, in combination with the screenwire,a sheet-metal strip having its upper edge bent over into a hook shape, and having its other edge bent and curved in cross-sectioma second sheet-metal strip held in the hook portion of the first sheet-metal strip and having its lower edge bent and curved in cross-section, to interlock with the bent curved edge of the first strip, said screen-wire being disposed between the two strips and held between and clamped by the upper edge of the second strip and the bent-over hook-shaped edge of the first strip substantially as shown and described.

4. A screen including a frame comprising, in combination with the screen-wire, a sheetmetal strip having its upper edge bent over into a hook shape and having its other edge bent and curved in cross-section, a second sheet-metal strip having its upper edge held in the hook portion of the first sheet-metal strip and having its lower edge bent and curved in cross-section to interlock with the bent curved edge of the first strip, said screen-wire being disposed between the two strips and held between and clamped by the upper edges of the said strips, and a stiffener-rod disposed within said frame, substantially as shown and described.

5. A screen including a frame comprising,

IIO

in combination with the screen-wire, a pair of interlocked sheet-metal strips 3 8", one of said strips 3, having an inwardly-bent portion 3 and an upwardly-extending portion 3 and a hook-shaped bent-over edge portion 3, said strip 3 being also provided with a U- shaped portion having; an inwardly-bent member 3" curved in cross-section, said second strip having an upper edge 3 for cooperating with the hook-shaped edge 3 and an inwardlybent member 3' for cooperating With the similarly-formed member 3", said first and second strips being so arranged as to hold the screen-Wire between their upper interlocked portions and to be interlocked with each other and said hook-shaped edge 3 being adapted to hold the screen-Wire in a vertical plane outside of the vertical plane of the second sheet-metal strip substantially as shown and for the purposes specified.
